Abstract

The utility model discloses a special-purpose voltage transformer test wiring device and belongs to the technical field of a wiring tool. The special-purpose voltage transformer test wiring device comprises lead, wherein the lead is provided with six secondary wiring clamps, a front end of the lead is provided with relatively longer wiring clamps, and distances from the secondary wiring clamps to the lead are set to be identical. When the special-purpose voltage transformer test wiring device is used, the secondary wiring clamps with identical length respectively clamp at secondary wiring terminals of 1a, 1n, 2a, 2n, da and dn of a voltage transformer, the wiring clamps with relatively longer length at the other end are in grounding connection or are led out to connect with wiring columns of a test instrument; when the field has no three groups of secondary windings, a secondary winding of the voltage transformer is in short circuit connection correspondingly, and other wiring clamps are free. The special-purpose voltage transformer test wiring device simplifies an operation process, further improves contact reliability and improves test efficiency. The special-purpose voltage transformer test wiring device has a simple structure, is safe and reliable, realizes labor saving and time saving and is relatively easy for popularization and use.

Description

A kind of voltage transformer (VT) test connection isolated plant
Technical field
The utility model belongs to the jointer technical field, particularly a kind of voltage transformer (VT) test connection isolated plant.
Background technology
Along with constant development of economy, power supply reliability requires also more and more higher.Mutual inductor is equipment important in the electric system, and following basic role is arranged: with parameters such as the electric current of electric meter and relay protection and aut.eq. conjunction measuring electric system high voltage circuit, voltage, electric energy; Isolated high voltage, safeguard work personnel and device security; It is unified that the mutual inductor secondary is surveyed ratings, is conducive to the secondary device standardization: be conducive to use low pressure, low cross section cable to finish the measurement defencive function.So whether mutual inductor is in good state, to the important role in safe operation of electric system.In order to guarantee the safe operation of mutual inductor, need be to the insulate test of project of mutual inductor, and winding requires the Insulation Test of Secondary Winding: first and second winding needs short circuit, at the scene because condition restriction, one time ratio of winding is easier to, the Secondary Winding short circuit adopts traditional method with the thin wire short circuit that following problem is arranged: the time is longer, need take each screw apart, tightens again; Thin wire comes off sometimes easily, need have special-purpose test connection device can guarantee that short circuit is firm, shorter sometimes.We have made mutual inductor test connection isolated plant.After adopting this device, can save a large amount of time, can guarantee that again short circuit is firm.CN 201654218 U disclose a kind of voltage transformer (VT) multi-function test stand, comprise control loop and test loop, the test loop is provided with pressure regulator, the pressure regulator input end is connected with gauge tap, output voltage regulator is connected with excitation test loop and error test loop respectively, this excitation test loop links to each other by one group of normally open contact of first contactor and the excitation test connection terminal of voltage transformer (VT), one group of normally open contact of second contactor in error test loop links to each other with the input end of an isolating transformer, the output terminal of isolating transformer inserts the primary side of standard potential transformer and the error test connection terminal of voltage transformer (VT) respectively, and the secondary side of standard potential transformer inserts the respective terminal of a mutual-inductor tester.Described voltage transformer (VT) multi-function test stand needs standard potential transformer first and second winding connection terminal to insert the respective terminal of sensor tester, but has terminal requirement height, the bad phenomenon of connection effect in being to use.
The utility model content
The utility model purpose is to solve voltage transformer secondary winding short circuit inconvenience problem, and a kind of voltage transformer (VT) test connection isolated plant esy to use, safe and reliable is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of voltage transformer (VT) test connection isolated plant, and it comprises lead, and described lead arranges six roots of sensation secondary connection clip, and described lead front end arranges the long connection clamp of length.
Described secondary connection clip is set to identical to described conductor spacing.
The utility model comprises secondary connection clip and connection clamp that length is long that six roots of sensation length is identical, the secondary connection clip that length is identical is clipped in respectively on 1a, 1n, 2a, 2n, da and the dn of secondary connection terminal of voltage transformer (VT) during use, and the described connection clamp ground connection that other end length is long or draw is connected on the test apparatus binding post; When the scene does not have three groups of Secondary Winding, remaining connection clamp sky gets rid of and gets final product behind the corresponding short circuit of voltage transformer secondary winding.The utility model has changed the method for traditional secondary winding short circuit with thin wire, effectively avoided complicated processes that each screw is taken apart, tightened, also having stopped to come off easily with thin wire causes contacting not firm phenomenon, can save a large amount of test periods, has improved efficient.The utility model is simple in structure, easy to operate, safe and reliable, time saving and energy saving, generally promotes the use of than being easier to.
Description of drawings
The utility model is further described below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use synoptic diagram of the present utility model.
Embodiment
As illustrated in figs. 1 and 2, a kind of voltage transformer (VT) test connection isolated plant, it comprises lead 1, and described lead 1 arranges six roots of sensation secondary connection clip 2, and described lead 1 front end arranges the long connection clamp 3 of length.
Described secondary connection clip 2 is set to identical to described lead 1 distance.
The utility model comprises secondary connection clip 2 and connection clamp 3 that length is long that six roots of sensation length is identical, the secondary connection clip 2 that length is identical is clipped in respectively on 1a, 1n, 2a, 2n, da and the dn of secondary connection terminal 5 of voltage transformer (VT) 4 during use, described connection clamp 3 ground connection that other end length is long or draw are connected on the test apparatus binding post, connect together with a winding tail end 6 simultaneously, realize short circuit simultaneously; When the scene does not have three groups of Secondary Winding, remaining connection clamp 2 skies get rid of and get final product behind the corresponding short circuit of described voltage transformer (VT) 4 Secondary Winding.The utility model has changed the method for traditional secondary winding short circuit with thin wire, effectively avoided complicated processes that each screw is taken apart, tightened, also having stopped to come off easily with thin wire causes contacting not firm phenomenon, can save a large amount of test periods, has improved efficient.The utility model is simple in structure, easy to operate, safe and reliable, time saving and energy saving, generally promotes the use of than being easier to.
